The default settings for Kitsune do not send email. However, outgoing email
is printed to the the command line. If you want to get email, you should
double check one thing first: are there any rows in the
notifications_eventwatch table? If there are, you may be sending email to
real users. The script in scripts/anonymize.sql will truncate this
table. Simply run it against your Kitsune database:

So now you know you aren’t emailing real users, but you’d still like to email
yourself and test email in general. There are a few settings you’ll need to
use.

First, set the EMAIL_BACKEND. This document assumes you’re using the SMTP
mail backend.

EMAIL_BACKEND='django.core.mail.backends.smtp.EmailBackend'

If you have sendmail installed and working, that should do it. However, you
might get caught in spam filters. An easy workaround for spam filters or not
having sendmail working is to send email via a Gmail account.

Yeah, you need to put your Gmail password in a plain text file on your
computer. It’s not for everyone. Be very careful copying and pasting
settings from kitsune/settings_local.py if you go this route.
